ing is a specification.

Our invention relates to cash indicators and registers; and it consistsin means for locking and unlocking the signals, independent means ofpreventing the registering-lever and the registe'ringratchet from beingcarried too far by their respective momentums, and thereby registeringtoo much, means of ringing the alarm-bell, and in the combinationshereinafter described and claimed.

In the accompanying drawings, on three sheets, Figure l is an isometricview of the mechanism of a cash indicator and register constructedaccording to our invention; Fig. 2, a rear elevation of a part of thesame, showing the signals, signal-rods, the grid, its operating-spring,its locking-hook, the lockingrod, and means of connecting saidlockingrod and grid, none of the signals being raised; Fig. 3, a rearelevation of the parts shown at the left in Fig. 2, showing one signalraised and the rear end of the corresponding keylever raised to move thegrid and thereby to operate the lockingrod; Fig. 4, a rear elevation ofthe signal and the upper part of its signal-rod and a part of theloekingrod, the latter being so broken as to show the projection on thefront of said locking-rod, which, by moving under a correspondingprojection on said signal-rod, supports said signal-rod;

hammer-operating lever, ils cam and support 0 ing-post, the upper partof the bolt or tillhoider, and'a section of the rocking plate on theline 3 3 in Fig. 8, the dotted lines showing the position of said leverwhen said hammer is raised to strike the bell; Fig. 7, a side elevationof the mechanism shown in Fig. 1 and a vertical section of the rockingplate on the line .2 z in Fig. 8; Fig. 8, a plan of the rocking plateand fulcrum-rod; Fig. 9, a left-side elevation of the locking-rod, itsdownward 6o projection, and the corresponding upward projection on thegrid, these parts being in a position to unlock the lockingrod; Fig. 10,a like elevation of the same parts after the lock ing-rod has beenreleased by the grid; Fig. 1], a plan of the registering-lever providedwith a longitudinal rib, the registering-ratchet, the stop-wheel, andparts of the key-levers nearest the registering-lever with their hooks;Fig.

12, a right-side elevation of the key-levers provided with hooks, theregistering-lever pro vided with alongitudinal rib,the rocking plate,the registering-ratchet, and stop-wheel and supporting-posts.

The case C, the key-levers K, turning on the fulcrum-rod F, said rodbeing supported in brackets or stands ff secured to the table 0 of thecase, the key-lever guides 7;, the signals S, supported upon verticalsignalrods S, each signal-rod resting upon one of said key-levers andbeing guided in horizontal guides C C supported upon vertical standardsC C, said signals and levers being correspondingly numbered, are allsubstantially as shown and described in Letters Patent No. 877,3l2,dated January 81, 1888. As in the patent referred to,the grid D consistsof vertical parallel rackbars (1, equal in number to the key-levers andconnected to each other, said grid being pivoted at (Z to the upper endsof parallel in go clined links (2, which links are pivoted at theirlower ends to brackets (1, fast on the table 0, a spring, (Z pressingagainst one of thelinks d to hold the notched sides of the rack-barsagainst the key-levers to hold up the rear ends of the key-levers whenthe key-levers are depressed, in the usual manner, the upper side,

(1 of each of the upper notches, (7., being longer than any of thenotches below it and overhanging such lower notches, so that when thekey-lever is engaged with the upper notch of its rack-bar, still furtherraising the rear end of the key-lever moves the grid until none of theteeth of said rack-bar are immediately below said keylever, as shown inFig. 3, the grid being held in this position by a grid-locking hook, D,pivoted on a bracket,

0, on the guide 0 catching over an upward projection, d, on the top ofthe grid to allow the key-lever to return to its position, substantiallyas shown and described in said patent. The links d being inclined, asshown, moving the grid to the right raises said grid. The verticalsignal-rods are provided with horizontal projections s, as in saidpatent; but these projections extend to the rear of thesignal-rods,instead of being forward projections, and the locking-rod Lis supported, substantially as described and shown in said patent, nponhorizontal studs Z, which enter the standards C 0*, except that thelocking-rod is in the rear of said standards and its locking projectionsZ extend forward instead of backward.

In the accompanying drawings the lockingrod is represented as forced tothe left, as one stands in front of the machine, by the, spring Z.Instead of the means shown in said patent for moving the locking-rodagainst the pressure of the spring Z, said rod is provided with adownward projection, Z, the lower end, I, of which is bent horizontallybackward, and the grid is provided with an upward projection, d", theupper end, d of which is bent horizontally forward and so arranged thatwhen the grid is moved against the pressure of its spring (I thehorizontal part of said last-named projection strikes against thehorizontal part Z" of the projection l and moves the locking-rod L andits locking projections Zto the right of the machine-that is, to theleft in Figs. 2, 3, and 4lto allow the projections 8 on the signal-rodsto pass the projections 1 as the signal-rods are raised. (See Figs. 2,4, 9, and 10.)

\Vhen the locking-rod is moved suliiciently to the right and the signalis fully raised by the same key-lever which moves the grid, saidlocking-rod is released by the rising of the grid and consequent liftingof the part 11 above the part 1*, and the locking-rod is again forced tothe left by its spring Z", bringing the projections Z on the locking-rodunder the corresponding projections s of any signal-rods which may beraised at the time. The return motion of the locking-rod takes placebefore the return motion of the key-lever K, while the grid is stillheld by the hook D and while the signatrod is held up by said key-lever.

The grid-unlocking lever M is a bent lever pivoted on a vertical post,P, at m, and having a rear arm, at, which extends nearly horizontallybackward under the grid-retaining hook D, (see Figs. 1, 2, 5, and 7,)and having also a downhanging front arm, mflslotted at its lower endatm", to receive and lit loosely the horizontal cylindrical pin I),which closes the end of the slot 1) in the rocking plate B. The rockingplate B is provided at its front edge with ears 0*, which receive thefulcrurn rod F and allow said plate to rock on said rod. Said rockingplate B rests on all the key-levers K back of the fulcrum-rod, so thatdepressing any key-lever will raise the rear edge of said plate andcarry the pin 1; upward in the slot an, and thereby (said slot beinginclined upward and backward) will depress the rear end of the lever Mand allow the free end of the hook D to fall and engage the projection don the grid D, as above described, the grid being at the same time movedto the right by the depression of the key-lever, as above explained.When the key-lever is released, the plate B is restored to position bythe contraction of a spiral spring, m, attached to the lower end of thepost P and to plate B, near its front edge, as shown in Fig. 5, therebyraising the rear end of said lever M and releasing the grid from thehook D by raising the latter.

The belt F is or may be precisely like the bolt shown in said patent,and its lower end is not therefore shown. It is sufficient to say thatsaid bolt is long enough to reach down into the till in front of theback of the same, or in front of a bracket secured to said back, to locksaid till, and that thelower end of the bolt is beveled in such a manneras to be raised by said back or bracket when thetill is pushed in, thedropping of the bolt by its own weight locking the till, as shown insaid patent.

The bolt Fis raised when any key-lever is de pressed, and the plate B isrocked by an arm, I), on said plate, which arm extends laterally andbackwardly under one of the earsf", with which the bolt F is provided.

The vertical hollow bracket f secured to the table 0, is used to guidethe bolt F verti cally, and is provided (see Figs. 1 and 6) with abackwardly-extending slotted arm, j'*, which receives and guides theT-shaped cam-piece H,said cam-piece having lateral cars It h,one, h, ofwhich rests on the arm b of the rocking plate, and is therefore raisedby the depression of any key-lever K and the consequent rocking of saidplate. The other car, h, of the cam-piece is inclined downward from backto front, both on the upper and under side. The post I is supported onthe table 0, and has pivoted to it at p the bell-crank lever N, thelower end of which has a laterally-projecting cam, a, of the same shapeas the ear h, and normally over but out of contact with said ear h, sothat when the cam-piece H is raised the lower end of said lever N isthrown forward, and its rear end is depressed until the ear rises abovethe cam 71., and the lever N swings back to position by its own gravity,aided by the bell-hammer and hammer-actuating spring. When therocking-plate B falls back to position, the cam-piece falls to positionof its own weight,in so doing crowding back the cam a and the lower endof the lever N, which, immediately after the camroo- IIO

piece reaches its position,swings forward over said cam-piece.

On the post P is secured the alarm-gong G, and above the gong on saidpost P is pivoted the bell-hammer 9. One end of the springstriking wire9 carries the hammer, and the other end thereof, after being wound, at9", about the pivot g, is secured to the post P in front of ahammer-lever, g, turning on said pivot g, the lower end of said leverresting against the under or left side of the strikingwire, allsubstantially as shown in said patent.

The upper end of the hammer-lever 9 extends under the rear end of thelever N, so that when any key-lever K is depressed the hammer-lever isrocked by the rocking plate and lever N, and when the lever N returns toposition the hammer-lever is turned back against the stop 9 and thehammer strikes the gong to call the attention of customers.

The registering devices shown in the drawings of the present applicationare substantially like those shown in Letters Patent No. 370,363,granted September 20, 1887, to said Webster, and consist of aregistering-lever,O, provided with a pawl, 0, which engages a ratchet,O, turning on the same center with said lever O, and having secured toit a onetoothed pinion, (not shown,) which engages with the teeth ofagear,0-,and turns said gear one toot-h at each complete revolution ofsaid ratchet O, the teeth of said ratchet and gear being numbered andthe lever turning said ratchet a number of teeth when any key-lever isdepressed equal to the number indicated by the figures borne by saidkey-lever, as fully described in said last-named patent.

\Vith the registering devices above named a ma be used the retainin andlockiu devices index-fingers, and lever-guides shown in said last-namedpatent. The registering-lever is in the present invention prevented frombeing turned too far by its own momentum and registering on the ratchet0 an amount greater than is marked on the depressed key-lever andindicated by the corresponding signal by hooks 73, secured on the top ofthe key-levers K, respectively, back of the registering-lever, as shownin Figs. 1 and 7, so that when any keylever is depressed to its greatestextent the book 75* on said key-lever is raised and carried forward overthe registering-lever, or over a longitudinal rib, 0, east or otherwisesecured on the back of said registering-lever, the length of the hooks rso varying inlength and distance from the fulcrum as to engage saidregistering-lever while the same rests upon their respective key-levers,and said key-levers are depressed to their greatest extent.

As an additional precaution, to prevent the ratchet O and theregistering-lever from moving too far, we secure to said ratchet 0,concentrically therewith, a stop wheel, 0 of larger diameter, and havingits teeth either straight or turned, as shown, in the other directionfrom the teeth of said ratchet O, and upon the vertical post P securedon the table 0 by a horizontal stud, q, we pivot the bent lever Q insuch a manner that the nearlyhorizontal upper arm, q, of said last-namedlever extends backward over the stop-wheel O, and will be forced intoengagement with the teeth thereofwhen the lower arm, of said lever Q isthrown forward or raised by lifting the rear edge of the rocking plateB, (that is, by the depression of any key-lever,) the end of the pin 1)above described entering a slot, g, in said lower arm, q", these partsbeing so arranged that when the ratchet O has turned the angulardistance measured by the number of teeth corresponding with the numberon the depressed key-lever the rear or pawl end of the lever engages theteeth of the stop wheel 0 and prevents said stop-wheel, and thereforethe ratchet 0, from turning farther. It will be seen that the lever Q isoperated in substantially the same manner as thelever M. \Vhen thekey-lever is let go and the rear edge of the plate B falls, the lever Qis thereby restored to position. The stop'lever Q and the stop-wheel Oabsolutely prevent an excessive registration.
